A technological audit can help in identifying infrastructure that isn’t operating efficiently. For example, replacing backwash filters with a dual-layer filtration system can help in reducing water consumption.

Why is benchmarking important?

Benchmarking is standard practice across all industries. It helps to set and achieve performance targets. With benchmarking, plant managers and plant operators can identify historical trends. This allows them to compare today's baseline performance and quantify it.

Is water the gold of the 21st century?

“Water is the gold of the 21st century.” #N#With the global water crisis increasing exponentially year-on-year, the need for reliable and efficient wastewater treatment plants is more than ever. Desalination and wastewater treatment plants should regularly analyse their equipment's performance to ensure that it's offering the maximum results.#N#While wastewater treatment technology has come a long way, inefficient operation is a pressing concern for wastewater treatment plant operators. Outdated water management techniques combined with older pumps can lead to higher operating costs, extended downtime, and reduced output – all of which negatively impact the bottom line.#N#As the leading supplier for pumps used in the water and wastewater industry, Sintech shares five smart ways to enhance wastewater treatment plant's efficiency, thereby improving outputs and reliability.

What is electrocoagulation based on?

It involves a current supplied to electrodes that are positioned within the solution to be treated. In electrolysis, a chemical reaction is induced in a substance in order to create other substances. For instance, electrolysis of salt water will produce sodium hydroxide, hydrogen gas, and chlorine gas.

Is wastewater treatment efficient?

While current treatment methods and technology is relatively effective, it is not as efficient as it could be. New treatment technologies have been designed specifically with increased effectiveness and efficiency in mind.

Is EC sludge toxic?

EC does produce sludge, but there is much less of it and it is easier to dewater. Disposal would not cost any extra, due to the sludge being non-toxic. The EC sludge can also potentially be used as a beneficial soil additive instead of simply being disposed of in a landfill.

Does an electrochemical treatment unit require training?

Operation of an Electrochemical treatment unit doesn’t require any particularly intensive training. Much of it can be set up to be done automatically with remote monitoring capability. In addition, due to this virtually non chemical process, any necessary adjustments for contaminants can be made by a quick pH adjustment or more or less power.

Why are pump stations important?

A significant portion of a utility’s energy usage is attributed to one or more pump stations used in virtually every community’s collection system. Older pumps were typically designed to operate at a single speed and on/off cycling. Today’s pump/motor/drive combinations are more efficient over a wider range of flows. Upgrading older pumps can produce long-lasting operation and maintenance savings. Inexpensive and more reliable variable frequency drives can also be used to match pump speeds to flow rates, further reducing energy needs.

What is the best opportunity to turn brown into green?

One such opportunity offering excellent potential is your wastewater treatment plant (WWTP) - turning brown into green.

How much energy does a wastewater treatment plant use?

Solids handling processes use over 20% of the energy at a wastewater treatment facility, and pumping and disposing of solids requires energy every step of the way. Options to save money and energy are abundant, from minimizing transported water and solids to utilizing biogas for producing electricity and heating water, also known as co-generation.

Is phosphorus a component of fertilizer?

Phosphorus is an essential component in fertilizers. If your plant is currently utilizing or evaluating biological phosphorus removal you may consider the feasibility of creating a marketable commercial grade fertilizer . This turns a necessary operational cost into a new source of revenue for the utility while improving sidestream performance of the plant by reducing phosphorus loading in the recycle streams.

What is SCADA in a plant?

Supervisory Control and Data Acquisition (SCADA) can provide real-time data on the treatment processes in your plant. SCADA can automate the operation of your plant or allow the operator to control the plant remotely. The system can monitor equipment and alert the operator of emerging issues. When properly planned and integrated, the SCADA system can provide operators with the desired amount of hands-on versus hands-free control, freeing operators to perform other duties. Continuous monitoring and trending of various processes and equipment can reveal periods when energy usage can be reduced or peak energy loads can be shaved.

How to eliminate hazardous chemicals?

Eliminate costly and hazardous chemicals by replacing your chlorine disinfection with an ultraviolet (UV) light disinfection system. Chlorine and dechlorination chemicals are expensive and energy-intensive to manufacture and transport.

How has sewage treatment improved?

Although sewage treatment has improved vastly since the passage of the Clean Water Act, after more than four decades of permitting treatment and discharge of sewage, communities across the country still dump pollutants into the nation’s waters that are harmful to fish and wildlife and humans. Everyone agrees that there has been significant improvement in the treatment of sewage, but billions of gallons of raw or partially treated sewage still make it to our waters every year through combined sewer overflows (systems designed to treat sewage and stormwater together), leaking pipes, and permitted “bypass.” Challenges to reducing sewage pollution and making improvements include:

Do wastewater treatment plants remove chemicals?

New chemical threats – new chemicals are approved every day and wastewater treatment plants do not remove all chemicals from sewage. For example, there are concerns about pharmaceuticals, microbeads, caffeine and many toxic contaminants that are not removed during the treatment process.
